1st Test on QO-100 DATV

-    DC Power supply 12/28v
-    Up converter, Adalm Pluto modified
-    RF power amplifier with Output 35/ 60 w (AMPLEON BLC2425M10LS250)
-    DATV receiver Minitioune V2
-    1,8m prime focus dish for TX. with Poty
-    80 cm offset dish for RX with Down Converter Khune.

 

1st tests with 80cm offset dish + helix + LNB, Pwr SSB = 10W

 

Experimentations in DATV mode

 1) Dish 1,8m on test + poty feed + LNB, DATV Pwr = 10W

01/08/2021

2) Dish 1,8m + Poty feed + Down converter Kuhne, DATV Pwr = 40W

Tests with Down converter KUHNE put in box

Tests with Power Amplifier from F4VSG @ 60w Output

No excess temperature, remains warm ( Abt 38 deg C) after 10 minutes tune.
